Application filed .Tune 21, 1910. Serial No. 568,211.

To all whom it may concern:

Be it known that I, WVILLIAM S. DU- oHARMn, a citizen of the UnitedStates, residing at Johns-town, in the county of Cambria and State ofPennsylvania, have invented a new and useful Vise, of which thefollowing is a specification.

It is the object of the present invention to provide an improvedconstruction of vise and more particularly an improved pipe vise and theinvention aims primarily to provide a device of this type in which apipe of any ordinary size may be readily disposed and quickly and firmlyclamped with but little manual exertion.

With the above and other objects in view, the invention consists in thegeneral construction and arrangement of parts shown in the accompanyingdrawings, in which,

Figure 1 is a View in slde elevation of a pipe vise constructed inaccordance with the present invention, Fig. 2 is a top plan viewthereof, Fig. 3 is a vertical transverse sectional view on the line 33of Fig. 1, and, Fig. 4.- is a view similar to Fig. 3 but illustrating aslight modification of the invention.

In the drawings, the vise is illustrated as embodying in itsconstruction a body 5 which is formed with a lateral wing 6 adapted tobe disposed upon and secured to the top of a work bench or similarsupport. The body 5 is formed in its upper face with a channel 7 and thefunction of this channel will be presently explained. A jaw post 8upstands from the upper face of the body 5 and the channel 7 and toopposite sides of this jaw post are secured jaw plates 9 which havetheir outer edges recessed as at 10. For a purpose to be presentlyexplained, the body 5 of the vise is formed in its upper face,rearwardly of the jaw post 8 with an upstanding boss 11 and this boss 1sspaced from the said rear face of the jaw post as clearly shown in Fig.1 of the drawings.

The movable jaw 12 of the vise is formed with a shank 13 and is formedin its upper edge with rack teeth 14:. The shank 13 is fitted slidablyin the channel 7 of the vise body and one wall of this channel is formedwith a groove 15 into which groove projects .a stud 16 formed upon thecorresponding side of the jaw shank 13.

A lever 17 is formed at its lower end with a plurality of teeth 18 andat its said end is inserted between the rear face of the jaw post 8 andthe forward face of the upstanding boss 11. A pivot pin or fulcrum 18 isthen driven through registering openings in the boss 11, the said lowerend of the lever 17, and the upstanding jaw post. From an inspection ofFig. 3 of the drawin s it will be observed that when. the lever 1s swungdown to the dotted line position shown in Fig. 3, its teeth will clearthe rack teeth 14 of the jaw shank, thus permitting the movable jaw tobe shifted into engagement with a pipe or like object to be held. Afterthis additional adjustment of the movable jaw has been accomplished, thelever is swung over in the direction indicated by the arrow in Fig. 3 ofthe drawings until it assumes about the position shown in full lines inthe said figure it being understood that as the lever is so swung, itsteeth 18 will come into meshing engagement with the rack teeth 14 andthe rack shank of the movable jaw will be drawn rearwardly, causing thesaid jaw to firmly bear against and clamp the aforesaid pipe or otherobject to be held in the vise.

From the foregoing description of the invention it will be understoodthere is providcd a vise in which the initial adjustment of the movablejaw may be rapidly made and clamping adjustment or movement of the jawaccomplished with but little manual exertion owing to the leverageafforded by the lever 17.

The form of vise shown in Fig. 4 of the drawings is identical with thatillustrated in Figs. 1, 2 and 3 except that whereas, in the said Figs.1, 2 and 3, the rack shank 14C of the movable jaw is of a width lessthan the width of the two lower ends of the lever 17, in this latterform, shown in Fig. 4, the shank is considerably broader and a groove 19of rack formation is formed in the upper face of the shank.

What is claimed is In a vise, a channeled body, a fixed jaw, upstandingfrom the body, the movable jaw having a rack shank slidably fitted inthe channel of the body, a boss formed upon the body and spaced withrelation to the said upstanding fixed jaw, a lever having its lower enddisposed between said fixed jaw and said boss, the said lever at itslower end having a plane face and arcuate teeth adapted to mesh with therack shank of the mov- 10 swung to another position its plane facevvillbe spaced above the teeth of theshank to permit of free movement of theshank. In testimony that I claim the foregoing as my own, I have heretoal'l ixed my signature in the presence of tWo Witnesses.

able jaw, and a pivot pin inserted through the boss, the said end of thelever and the said fixed jaw, the distance between the said plane faceof the lever and the pivot for the lever being less than the distancebetween the said pivot and the upper end of the teeth of the shank ofthe movable jaw, whereby when the lever is in one position it will meshwith the rack shank and when
